Sex-biased migration and demographic history of the big European firefly Lampyris noctiluca

This study investigates the demographic history and sex-biased migration patterns of Lampyris noctiluca, revealing a complex colonization history with maternal and male-only migration routes.

Sudden shifts in expression after small-scale duplication in vertebrates and strong support for the ortholog conjecture

The paper tests the ortholog conjecture by analyzing gene expression shifts after duplication in vertebrates, finding strong support for the conjecture and showing trait jumps affect small-scale paralogs more than genome-wide duplicates.

Population genomics and epigenomics provide insights into the evolution of facultative asexuality in plants

The paper analyzes population genomes and epigenomes of Spirodela polyrhiza to show low genomic diversity and DNA methylation levels, with natural selection shaping asexual reproduction traits.

Evidence of active oviposition avoidance to systemically applied imidacloprid in the Colorado Potato Beetle (Leptinotarsa decemlineata)

This study shows that Colorado Potato Beetle females actively avoid ovipositing on imidacloprid-treated plants, suggesting learned behavior contributes to their resistance and spread.

A Time-calibrated Firefly (Coleoptera: Lampyridae) Phylogeny: Using Genomic Data for Divergence Time Estimation

The paper estimates a time-calibrated firefly phylogeny using genomic data and evaluates the impact of data subset selection and model adequacy on divergence time estimation.

A cautionary note on the use of haplotype callers in Phylogenomics

The paper compares GATK and ATLAS haplotype callers in phylogenomic studies, showing GATK underestimates variants at the phylogenetic level but not population level.

On the effect of asymmetrical trait inheritance on models of trait evolution

This study investigates how asymmetrical trait inheritance at speciation affects macroevolutionary analyses, showing that small phenotypic jumps can significantly alter model selection and parameter estimation.

On the inference of a southern origin of the North American firefly Photinus pyralis

This study infers the origin of Photinus pyralis in Central or South America and traces its colonization of North America using demographic modeling and RAD data.

Linking micro and macroevolution in the presence of migration

This paper introduces an OU model that incorporates migration during speciation to study trait evolution and phenotypic disparity across phylogenies, showing migration reduces disparity and affects inference.

Inference of evolutionary jumps in large phylogenies using Levy processes

The paper develops an efficient algorithm to infer evolutionary jumps in large phylogenies and applies it to Anolis lizards and Loriini parrots, finding strong signals at the bases of clades transitioning into new adaptive zones.
